shoestring

I did the switch mod on a mega-drive recently for a friend who wanted to play sonic in NTSC. We had video going into a philips CM8833, apart from the black and white picture the game played much better. The only solution was to use the RGB scart cable, beautiful picture. NTSC is much better for these types of games. If you want NTSC and PAL in one monitor the Sony PVM is a good option, expensive though. I just recently picked up a PVM-9041QM that takes RGB, composite, component and svideo.

I recommend installing the SCCC with the video cable internally straight to the monitor port. It's a little more work as you have to lift some components in the video output section but it's worth it. I just couldn't bring myself to drill a hole in the plastic case after routing the cable through the existing hole in the metal cage.

Based on the position, most likely a kernal rom switcher ( speeddos / jiffy dos )

You can have mine. I placed an order but no longer want it...

Amiga did games very well. To be honest I don't think the programmers that were porting arcade games to the Amiga really had the opportunity to take advantage of the Amiga's chipset. It was a case of getting the games out as fast as possible. The end result was a 'lazy port' from the ST or just a shitty port in general ( see Double Dragon ). There were some really good ports to the Amiga though.. Final Fight wasn't too bad, Golden Axe, Ghosts and Goblins, Silkworm, Ghouls & Ghosts and Mortal Kombat. Amiga's hardware was unusual for a games system though, it had to use the blitter for everything and there was no tile based mode like in the x68000 ( you had to do it in software ) which seem to limit the machine's performance / frame rate of shooter style games down to ~25fps vs 50-60fps in the arcades. With a tiling mode in addition to a blitter, the Amiga would have been untouchable in every department. But we have to remember that the Amiga was designed with a specific budget in mind... the blitter / line drawing capabilities of the Amiga is a feature that gives us all of these amazing demos.

Amiga suffered from "lazy ports" though didn't it ?. There were a lot of games that were written for the ST first and then ported straight to the Amiga without taking advantage of Amiga's extra hardware features. There was no way for the Amiga to compete in this area, it doesn't have decent text-modes that the PC excels in.

Nothing short of amazing!

It's shut down by asserting RDY and AEC. I suspect they did this to facilitate things like the CP/M cartridge, which contained a Z80

Have heard and read a lot about them but i've never seen one, probably a myth. Someone please prove me wrong because I'd like one... I have one and it's gone. You're one of the lucky ones.

Love the marshall amp in the background

CRT monitors are fairly fragile to ship. When I said something may have moved inside, what I meant was the larger components soldered to the chassis, they don’t have much support if the unit gets thrown around during shipping . Solder that was used to assemble Commodore “branded” monitors was not the best quality and often need reflowing.

Was working before it was moved when the previous owner tested so something shifted inside during transit. Is there any neck glow when plugged in? No power light or neck glow could indicate an issue with the flyback. When those usually fail it's spectacular and you'll hear a horrible whiny sound everytime the monitor is powered up

I think you mean the 6800 ?

Yet Woz couldn't get his computer to work. Chuck drove over the garage and helped them getting the 6502 to work in the Apple 1.

The "heavy lifting" was done by MOS Technologies via the introduction of the 6502. But of course there was no innovation there too right ? Because the company that built the chip was part of Commodore This thread has become ridiculous to say the least. Even Woz remarked that the c64 was a truly "ground breaking" system. https://www.techrepublic.com/blog/tech-decision-maker/commodore-pioneer-jack-tramiel-dies-wozniak-industry-and-tech-pros-react/

It took a year or so before c64 sales really started kicking in and this was due to reliability issues and lack of software at the time. Not purely due to price. People are smart enough to realise what they're going to get before paying for it. There were other affordable machines ( eg.. ZX Spectrum series which did very well in the U.K ) available at the time retailing for less than the c64 but weren't quite as successful in sales. Commodore really got behind the c64 and provided developers with documentation and technical info so they could write better titles for it and because of that, software houses saw the potential in the machine and what the platform could offer... it really took off from that point on. Well, he was kinda right wasn't he?. I mean without Jack Tramiel stepping in and buying the company.

Quite interesting. There’s definitely an Amiga 1200 in the background behind her. https://m.youtube.com/watch?v=QqxThgLTLyk

I was just a little disappointed that the first list left out the AA ( Acorn Archimedes ) completely. I mean, it definitely deserves a mention. Look at all your modem day handheld devices. The ARM250 was innovative for 1992, a complete computer system fits on a single chip. ( MEMC, VIDC, IOEB and IOC ).

I actually prefer this list to be honest.. https://www.stuff.tv/news/25-most-iconic-computers-ever

Sorry to hear. Which is why I hate shipping or having vintage monitors shipped. It's possible the transit as put stress some on the solder joints, especially around the fly back. If you decide to open the back of the monitor, discharge the tube first.

The switch is prone to failure, so it's not a matter of if it fails but when. Use a small piece of cardboard to hold it in for now.

Never replaced one on a 1702 Not my auction. https://www.ebay.com.au/itm/COMMODORE-CRT-MONITOR-1084S-1940-1941-1942-OTHERS-REPLACEMENT-POWER-SWITCH/253718802415?hash=item3b12d1afef:g:Sj0AAOSwCcZaS8CA:rk:1:pf:0 Don't they all use the same switch ?

Keeping the chipset the same throughout the 8-bit line was a mistake IMO, that didn't do Atari any favours. They simply were not able to produce a low cost machine quick enough to compete with the c64. This allowed the c64 to gain momentum and surpass it in sales whilst its price dropped to a point where nobody was able to compete. Commodore had a very strong supply chain here in Australia, something Atari lacked. I don't understand how anyone can consider having multiple models ( 16kb to 64kb machines ) with the same chipset an advantage. There were far too many models to choose from. Would have been better had they focused on marketing the 800xl and retailing it at a competitive price.

Both machines were a compromise. The Atari has more restrictions due to lack of char colour ram. If you look at the later c64 european titles. Apart from the fixed colour palette of the c64, it was a much better compromise with an excellent range of standard colours.

Could be playing blind. Loading some software via ASPEQT / SIO should confirm if the machine is working. I had a dodgy modulator in one of my A8s when I was trying to troubleshoot other issues, re-flowing fixed it.
